Abstract

The invention discloses a framework arc-shaped structure of an intravascular medical apparatus. The mesh basket shaped membrane-covered intravascular medical apparatus is provided with three or more framework silk threads which are of arc-shaped structures, and each framework silk thread forming the apparatus is arc-shaped, so that each framework of the mesh basket shaped apparatus is delivered in a catheter, the arc-shaped framework silk threads are pulled to be in a straight line shape, and the framework silk threads and the delivery catheter wall do not form point contact but form line-shaped large-area contact. The frameworks formed by the arc-shaped thin threads are easily transformed into straight lines to penetrate through the catheter. Accordingly the pushing performance and flexible-smooth performance of the apparatus are highlighted and improved, and delivery by means of micro-catheter and other flexible catheters is achieved.

Description

A kind of skeleton cambered structure of Ink vessel transfusing medical apparatus and instruments
Technical field
The present invention relates to medical instruments field, relate to a kind of skeleton cambered structure of Ink vessel transfusing medical apparatus and instruments specifically.
Background technology
Ink vessel transfusing medical basket shape apparatus in action before, source of disease position need be reached through conveying in conduit and just can play basket and derive after conduit and automatically expand, then play a role.At present be applied to the propelling movement segment length of endovascular basket shape apparatus through microtubular all long, the front end basket worked is all by having the filament materials of memory performance to be made up of angle shape skeleton.This has the shortcoming of angle shape structure to be, when delivery conduit be flexible conduit, particularly microtubular time, due to the angle shape of the wire rod of longer propelling movement distance, front end basket, every rhizoid line of composition basket is angled to be acted on catheter wall, cause effect contact area little, cause the outer swollen power of site of action maximum, therefore have the basket shape apparatus of angle shape cannot realize carrying in flexible microtubule.
When carrying in conduit, require that basket structure is straightened linearly.Angled silk thread shape straightens needs the strength more much larger than radian shape shape, and the silk thread frame configuration in radian is easy to be drawn as linearity, the silk thread shape basket structure that Here it is angularly cannot by the reason place of soft microtubular conveying as the basket of radian shape skeleton.
Summary of the invention
For deficiency of the prior art, the technical problem to be solved in the present invention there are provided a kind of skeleton cambered structure of Ink vessel transfusing medical apparatus and instruments.
For solving the problems of the technologies described above, the present invention is realized by following scheme: a kind of skeleton cambered structure of Ink vessel transfusing medical apparatus and instruments, this structure comprises at least three skeleton silk threads, described skeleton silk thread introducer imports in small-bore microtubular, described skeleton silk thread is the arcuation of evagination, and every root skeleton silk thread point angle links into an integrated entity, form basket shape, the skeleton of silk thread shape is easy to be drawn as linearity, whole basket becomes linearity and carries through microtubular, skeleton due to radian fine rule formation is easy to change into linearity and passes through conduit, give prominence to and improve the propelling movement performance of this type of apparatus and submissive performance, reaching can through microtubular or other soft tube chamber conveying, when every root skeleton of basket shape medical apparatus and instruments is carried in microtubular, the skeleton silk thread in radian is drawn as linearity, is not the contact of point, and presents the bump contact of linear with carrier wall, the skeleton that radian skeleton silk thread is formed is easy to change into linearity and passes through microtubular.
Further, the radian of described skeleton silk thread is set to 120 ~ 180 degree.
Further, the radius of described skeleton silk thread is 0.0035 inch.
Further, the angle between skeleton silk thread is equal.
Further, described microtubular diameter is between 0.05 ~ 0.1 inch.
Further, described microtubular length is between 1 ~ 1.5 meter.
Relative to prior art, the invention has the beneficial effects as follows: the skeleton silk thread that the invention provides three or many is the basket shape band film intravascular devices in radian shape configuration, the every root skeleton silk thread forming this apparatus is radian shape, when every root skeleton of basket shape apparatus is carried in conduit, skeleton silk thread in radian is drawn as linearity, with the contact that carrier wall is not point, and present the bump contact of linear; The skeleton that radian fine rule is formed is easy to change into linearity and passes through conduit.Thus outstanding improve the propelling movement performance of this type of apparatus and submissive performance, reaching can through microtubular or other soft tube chamber conveying.

Fig. 4 is the radian schematic diagram of the single wire skeleton of Fig. 3 of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical scheme of the present invention is explained in detail.
As shown in Figure 1, the skeleton of this apparatus is that a radian skeleton silk thread point angle of giving prominence to configuration is integrally connected and forms by three or more root skeleton silk threads, when being imported in small-bore microtubular by introducer, the skeleton of silk thread shape is easy to be drawn as linearity, whole basket becomes linearity and carries through conduit, achieves and carries in flexible microtubule.The skeleton formed due to radian fine rule is easy to change into linearity by conduit, gives prominence to and improves the propelling movement performance of this type of apparatus and submissive performance, and reaching can through microtubular or other soft tube chamber conveying.
Please refer to accompanying drawing 1 ~ 2, the skeleton cambered structure of a kind of Ink vessel transfusing medical apparatus and instruments of the present invention, this structure comprises at least three skeleton silk threads 2, described skeleton silk thread 2 introducer imports in small-bore microtubular 1, the arcuation of described skeleton silk thread 2 in evagination, and every root skeleton silk thread 2 points of angles link into an integrated entity, form basket shape, the skeleton of silk thread shape is easy to be drawn as linearity, whole basket becomes linearity and carries through microtubular 2, skeleton due to radian fine rule formation is easy to change into linearity and passes through conduit, give prominence to and improve the propelling movement performance of this type of apparatus and submissive performance, reaching can through microtubular 2 or other soft tube chamber conveying, when every root skeleton of basket shape medical apparatus and instruments is carried in microtubular 2, the skeleton silk thread 2 in radian is drawn as linearity, is not the contact of point, and presents the bump contact of linear with carrier wall, the skeleton that radian skeleton silk thread 2 is formed is easy to change into linearity by microtubular 2.The radian of described skeleton silk thread 2 is set to 120 ~ 180 degree, and the radius of described skeleton silk thread 2 is 0.0035 inch, and the angle between skeleton silk thread 2 is equal, and described microtubular 1 diameter is between 0.05 ~ 0.1 inch, and described microtubular 1 length is between 1 ~ 1.5 meter.
